Detailed Solution

Chromosome 1 was the last of the human chromosomes to be sequenced. Its sequencing was completed in May 2006. There were many factors that contributed to the sequencing of chromosome 1 being one of the last steps in the HGP, including the size of the chromosome (it is the largest human chromosome with 2968 genes), the complexity of the sequence (chromosome 1 contains a high number of repetitive DNA sequences, which can be difficult to analyse), and the technical challenges involved in analysing the data.

Human chromosome 1 has most genes (2968 genes) while Y chromosome has the fewest (231 genes).
